GRAIN-SEPARATOR.

Application filed February 1 1, 1:119.

To all whom it may concern Be it known that I, HUGO E. BEI-IRENS, a citizen of the United States, residing at Fargo, in the county of Cass and State of North Dakota, have invented new and useful improvements in Grain-Separators, of which the following is a specification.

This invention has reference to improvements in grain separators.

The object of the invention is to produce a simple device of this character whereby l-cinghead and cookie seed will be easily and et'fectively separated from the wheat.

Other objects and advantages will appear as the nature of the invention is better understood, rcl'eri'ance being had to the accomuinying drawings, in which:

i igure l. is a vertical longitudinal sectional view through a separator constructed in accmfdance with this il'ivention.

Fig. 2 is a sectional view approximately on the line 2-2 0i Fig. 1.

ig 3 is a greatly enlarged sectional view approximately on the line 38 of Fig. 1.

ii it: is a persp ctive view of a portion of the screen.

Referring now to the drawings in detail, the separator is broadly indicated by the mun-oral 10, having at one end thereof a hopper 11. In the outlet mouth of this hopper is a revoluble feed 12, any suitable power being employed for turning the said :leed, and the feed is in the nature of a rectangular strip preferably provided with extending corners. At the outlet mouth of the hopper 11 is arranged a directing spout 13 having an angle outlet l-il directed inward of the separator and being disposed a considerable distance above a pan 15. In the separator is arranged a fan casing 16 having a revoluble fan 17 therein, the casing being provided with an outlet spout that is disposed at a downward angle and which is arranged over the pan 15. The spout is indicated by the numeral. 18.

Below the pan 15 is an angularly arranged sieve 19, and to the rear of the sieve Specification of Letters Patent.

Patented July 13, 1920. sari-nits. 277,010.

an angularly disposed deflector plate 20. l'he deflector plate is arranged at an outward angle, while the sieve 19 is arranged at a downward angle. The deflector 20 is positioned onlv a slight distance from the pan l5, and as the wheat is fed from the hopper and is delivered onto the pan 15 through the spout 14, the blasts of air from the fan 17 through the spout 18 will bring light foreign matter, such as kinghead, etc., over the pan into contact with the angle deflector 52d, and from thence out of the separator, the wheat grain being delivered from the tan onto the sieve l9.

The sieve 19 is of a particular and peculiar construction, comprising a flat plate formed with spaced series of contact memhers for the grain. lhese contact members are provided by slitting the plate 19 transver ely, as MP2], and longitudinall as at 5252. The plate may be scored from the ends of the slits 21 and 22, and the metal bounded by the slits is bent upwardly at an angle providing ears 23 and substantially V- shaped openings 241 between the ears. Each of the ears is provided with a round opening 25, and through these openings the cookie seed which are smaller than the wheat seed are passed when the grain gravitates on the sieve 19.

It is believed, from the foregoing descrip tion, when taken in connection with the drawings, the simplicity and advantages of the construction will be readily apparent without further detailed description.

Having thus described the invention, what 7 is claimed as new is In combination with a grain separator having a feed plate a sieve disposed below and spaced from said plate, said sieve comprising a body having converging ears up struck therefrom and arranged in pairs thereon and providing Vshaped openings below the same, each of said ears having an aperture therein.

In testimony whereof I affix my signature.
